From 1e1bddf15a1720917b11e44dc639351ad613c3dc Mon Sep 17 00:00:00 2001 From: Andres Rodriguez Date: Fri, 13 Jan 2017 18:44:17 -0500 Subject: [PATCH] radv: make device extension setup dynamic Each physical device may have different extensions than one another. Furthermore, depending on the software stack, some extensions may not be accessible. If an extension is conditional, it can be registered only when necessary. v2: removed unused function and fixed indentation Signed-off-by: Andres Rodriguez Reviewed-by: Bas Nieuwenhuizen --- src/amd/vulkan/radv_device.c | 189 ++++++++++++++++++++++------------ src/amd/vulkan/radv_private.h | 6 ++ 2 files changed, 130 insertions(+), 65 deletions(-) diff --git a/src/amd/vulkan/radv_device.c b/src/amd/vulkan/radv_device.c index e0991d4746c..08a1bf301ee 100644 --- a/src/amd/vulkan/radv_device.c +++ b/src/amd/vulkan/radv_device.c @@ -77,6 +77,108 @@ radv_device_get_cache_uuid(enum radeon_family family, void *uuid) return 0;
